Specifies the reference measurement procedures for cabling parameters and the requirements for field tester accuracy to measure cabling parameters identified in AS/NZS 3080. This Standard is an adoption of IEC 61935-1:2000.

This part of IEC 61935 specifies reference measurement procedures for cabling parameters and the requirements for field tester accuracy to measure cabling parameters identified in ISO/IEC 11801. References in this Standard to ISO/IEC 11801 mean ISO/IEC 11801 or equivalent cabling Standards. This Standard applies when the cable assemblies are constructed of cables complying with IEC 61156-1, IEC 61156-2, IEC 61156-3 or IEC 61156-4, and of connecting hardware as specified in IEC 60603-7 or IEC 60807-8. In the case where cables and/or connectors do not comply with these standards, then additional tests may be required. This Standard relates to performance with respect to 100 ohms, 120 ohms or 150 ohms cabling.
